How to update your smartphone

The firmware will be released to unlocked (sim free) handsets by end of this month (March). Owners of carrier branded (locked) smartphones might have to wait a bit longer. Once the firmware is released, the update can be installed using the LG Mobile Support Tool (available for Microsoft Windows PC). It looks like it won't be available as an OTA update this time, but we'll see.

To perform the Jelly Bean update, just follow this "step by step" guide:

Click on "Install USB Driver" and choose your smartphone model (4X HD = P880, P700 = L7, L9 = P670) and wait for the download to complete. In case the driver is not installed properly, you can find it on c:\device_name (eg c:\P880 for P880 Optimus 4X HD).

Make sure that the "USB mass storage mode" or "Media transfer mode" is not enabled on your smartphone. Disable this option under Settings/Memory Management/USB storage. Just select the "PC Software" mode.
